Hi Kenny,
I see two options.
Spread the attach points over a longer area or eliminate the attach points by using a 3 piece wing.
I have had some discussion with Dieter Reich the designer of the ULF-1. He agreed a 3 piece wing is a better solution which eliminates the heavy attach hardware.
Dieter is a brilliant man. He was chief engineer on a project that the Navy called his plane Tomcat I believe. At the time he had designed the faster aircraft on the planet and as a pet project the lightest foot launched sailplane ever. Talk about both ends of the spectrum..
